C^2 = A^2 + B^2
C^2 = 15^2 + 20^2
C^2 = 225 + 400
C^2 = 625
C = √(625)
C = 25
Answer:
The correct option is a=5, b = -4, c=7 ....
Step-by-step explanation:
The standard form is ax²+bx+c=0
where a, b, and c being constants, or numerical coefficients, and x is an unknown variable.
The given expression is:
4x + 5x2 = 8x – 7
To make it a standard equation we will move all the values to the left hand side and 0 will be left at the right hand side.
4x+5x²-8x+7=0
Now solve the like terms and arrange the equation according to the standard form:
ax²+bx+c=0
5x² - 4x +7 =0
Here a = 5
b = -4
c= 7
Thus the correct option is a=5, b = -4, c=7 ....
15/100 = x/82. I think that could be a proportion.
Total profit = total amount earned - cost of ingredients
P = 5s - 1160
Vertical angles are always equal. The vertical angles are the ones opposite each other. Therefore x would equal 40.
